Antony Clince Alex d2919409e9 gpu: nvgpu: rename/collpase nvgpu_next functions and structs
Replace all nvgpu_next functions/structs either by 1) collapsing them
into nvgpu legacy functions/structs 2) renaming them as follows:
- nvgpu_next_*() => nvgpu_(ga10b/ga100)_*()
- nvgpu_next_*() => (ga10b/ga100)_*()
- nvgpu_next_*() => nvgpu_*() [only if this doesn't cause collision]
- nvgpu_next_*() = > nvgpu_*_extra()

Create hal.sim unit and move Ampere+ SIM code into it.

Jira NVGPU-4771
